I probably went too far with this old POS to begin with, just about everything in it has been replaced from the starter cap to the motor to the open/close. All except for the stupid timer that's at issue now.

Thanks for the offer! Not sure I could mount it in the case though. Your reply gave me some good search terms I'll poke around with in case a guardian angel doesn't have one of these or a mindless replacement for same laying around
: Otherwise, get one of the youngsters to learn 'ya about solid state time : delay relays.
Any particular technology I should look for in these? The primary has to pass a good 10 amps worth of 110v inductive motor load, and the lamps ought to stay on for 2 or 3 minutes, maybe 240 watts on the lights (includes a 2x safety factor)(why do i care about safety I dont know, my sanity is gone from playing with this darned thing anyway)
